- Vectors 11798
- Vectors represent a horizontal slice of a column. They hold a number of values of a specific type, similar to an array. Vectors are the core data representation used in DuckDB. Vectors are typically stored within data chunks . The vector an

- Execution Format 10189
- Vector is the container format used to store in-memory data during execution. DataChunk is a collection of Vectors, used for instance to represent a column list in a PhysicalProjection operator. Data Flow DuckDB uses a vectorized query exec

- WITH Clause 7655
- The WITH clause allows you to specify common table expressions (CTEs). Regular (non-recursive) common-table-expressions are essentially views that are limited in scope to a particular query. CTEs can reference each other and can be nested.
...is not always possible, even if the heuristics are met. For example, if the CTE contains a read_csv function, it cannot be inlined. Take the following query for example, which invokes the same CTE three times: WITH t(x) AS (⟨complex_query⟩) SELECT * FRO...difying CTE as MATERIALIZED when later parts of the query depend on the modification having already run, so that it is not inlined or executed more than once.
